LabVIEW 2013 Executable stopped sending Emails a few days ago using the corporate email server.

I found out the program would no longer send emails using LabVIEW 2013 in either development or executable.  No errors were generated.

Solved the problem by switching to LabVIEW 2014.  Hope this helps others.

Here is the block diagram for those that are interested.
